Spares availability for 1928 Model 18

I have a very strong feeling that the VMCC would be a better place to ask that question?

I thought long and hard before I wrote that, BTW.

That said, if you can afford it, I'd take it.

If you find you can't get something you can get it made. Almost whatever it costs it will be worth it. If you have second thoughts, I'm prepared to take it off your hands...some hope!
